STEPHEN MESSERER, OF NEWARK, NEW JERSEY, ASSIGN OR TO THE MESSERER AUTOMOBILE COMPANY, OF NEW JERSEY.

srrcirrcnrron forming part of Letters Patent No. aegee e, dated Juiy 31, 1900.

Application filed J'uneS, 189i). `Serial No. 719,862. (No modell) n n Beit known that 1, STEPHEN MEssERER, a citizen of the United States, residing in the city of Newark, county of Essex, andV State of New Jersey,have invented certain new' and luseful Improvements in Gasolene-Motors, of which the following is a full, clear, and exact description ofthe invention, such as will en` able others Askilledin the art to which itap pertains to make and use thesame, reference being had to theaccompanyin g drawings, and to letters of reference 'marked thereon, which form a part of this specification.

This invention relates to improvements in gasolene-motors and other engines; and it consists in the combination, with an explosion-cylinder, of a second or auxiliary cylinder connected thereto, a piston placed in said second cylinder, and a suitable mechanism for retracting the piston in the auxiliary cyl inder so as to form a partial vacuum therein just as the discharge from the explosion-cylinder takes place, and a suitable mechanism. for slowly returning the piston to position, and thus slowly force the burned gases there-- from, all of which will be more fully described hereinafter.

The invention consists, furthermore, in the novel arrangements and combinations of the various parts, as well as in the details of the construction thereof, all of which will be fully set forth in the accompanying specification and then finally embodied in the clauses of the claim. l

The primary objectof this invention isvto provide a means for receiving the exhaust# gases from the explosion-chamber of the gasolenemotor, and thus prevent the exhaustgases from being discharged directly into the atmosphere and causing objectionable noises.

The invention is clearly illustrated in the accompanying drawings, in which-1- Figure lisan elevation of one form of gaso iene-motor, showing my invention applied thereto, the muffler being represented* partly in section. Fig. 2 represents an edge view and a vertical section of afc'am employed with my presentinvention, and Fig is a section taken through line :n in said Fig. 1. Fig.

4 is a side elevation of a portion of the explosion chamber or cylinder of the engine and avertical representation of a valve-cas ing connected therewith, illustrating one arrangement of thedischarge-port from the cylinder into said casing; also, the arrangementof an intake or Vin dmtion valve, as well i as the exhaust or relief valve, and portions of a bell-crank lever for actuating said exhaust or relief valve.` i Figf is a vertical cross-section of the various parts represented iiisaid Fig. 4, said sectionI being taken on line 5 5 in Fig. 4 and looking in the direction of the arrow y' in said iigure. Fig. 6 is a horizontal section of said valve-casing, taken on line 6 6 in Fig. 5, looking in the direction of 'arrow z, the cylinder of the engine being represented in top view, except a portion, which is broken away and illustrates in section a representation of the side wall of the cylinder with its exhaust-port leading into the valve-casing, the exhaust-valve in this View being illustrated in plan,\but a portion of a Vdividingwall in which the valve-seat is arranged being broken away to illustrate the outlet from said casing for the exhaust-gases into the auxiliary chamber or cylinder.

Similar numerals of reference are employed in all of the said above-described views to indicate corresponding parts.

In said drawings, l represents anysuitable framework to which the gasolene-motor 2 is Secured.A Upon the crank-shaft 4 is secured the fly-wheel 5, and connectedto this crankshaft in the usual manner is a piston 3 in the explosion-chamber 6. Also secured to the crank-shaft 4 is apinion7, which meshes with a gear-wheel 8, placed upon the shaft 8', and which wheel is provided with a cam 9 upon one side. This cam serves to operate a bellcrank lever 11, which is crankeshaped and is pivoted at 40. At its upper 1end this bellcrank lever is provided with africtionroller 10, where it comes in contact with thewcain 9. That portion of the lever below this' pivot 40 ,is much greaterthan that aboveit, and this lower portionll'lh'as secured to its outer end a bell-crank lever 35 forA operating the spring-actuated stem 37 of a valve'l2 upon the side of the exhaust connected with the engine-cylinder. The said roller l0 remains at all times in contact with the cam, and at each revolution of the cam the upper end of IOO `the lever 11 isforced forward, so that thebellcrank lever is operated.

As will be seen from an inspection of Figs. 4, 5, and 6 of the drawings, the cylinder 2 is provided in one side V,at or near its forward end with a port 2,through which., the expended gases are `florcedbythejreturn ofthe piston 3 in said cylinder 2 into fa suitablyconstructed valve-casing 28, suitably secured to the side of the cylinder 2 by means of` lugs `29 and screws or bolts 30, sub'stantiallyas illustrated. Said valve-casing 28 is provided.MA

with an intake or. du.ct.31, .which communi. cates with a duct 31', normally closed by a. spring-actuated valve 32, which is openedfby.

suction from the movingp-iston 3 in the -cyfl` asclearly indieatedin Figs. 4and 6. The said lever 35 is pivotally connected with the bellcrankL lever l2 at 38 and is preferably pro-` vided atv its lower end with al roller 39,'which 'is in operative engagement ,with the lower end of` thevalve-stem 37 for raising the valve 12 in the mannerm'eviouslv stated. Alsosecured to the crank-shaft 4 is a gear-wheel 13, which mesheswith agear-Wheel 14, securedv to the shaft 16, and to which shaft 16 is also secured a cam 17 which as it sweeps around strikes against the-friction-roller 2O upon the lever 19. This lever 19 is pivoted at its u pper endto the under side of the framework l and, has secured thereto a spring 23 for'the purpose of returning the lever to its initial position after having been operated bythe cam 17. Thesaid lever 19 has pivoted to its lower end the` piston-rod 2l, and thisrod is in turn secured to the piston24, which works in a; cylinder 22 for mailling the sound of the exhaust.- Also pivoted upon the cam 17 and having its outer edge projecting through the outer end of the'cam is an auxiliarycam 18, Whichis provided with a pin 15, whichextends ijntoand vprojects through a Islot 25 in the sidefofsaid cam 17 This auxiliary cam f18-is held pressed outward by means of a spring 26,v so that the outer end of the cam 418 `is made tof always project through the openingnear the extreme outer point of the carn17,and thus come in contactlwith the roller. 2O` upon the-lever 19. By bearing against the said roller the cam-surface of the cam 1.7- during therotation ofthe shaft 1,6

. forces-thelever19 slowly forward v until the said cam-surface has fully passed the roller;` butthemoment thepointof the cam 17 slips from the roller- 20 the spring 23 suddenly jerksorpulls the lever 19 backward, and thus permits the spring 23 towithdraw the-pis ton 24- suddenly from the inner end ofthe cylinder 22, and ythereby create a Vacuum or a partial vacuum into Whichthe exhaust from the explosion-chamber 6 of thel cylinder 2 is received. As will-be seen, the point Qf` the cam 18 extends beyond the point of the cam 17, and thus serves to keep the le,- -ver 19 pressed forward after the cam 17 has `passed beyond it.` The samey effect can be producedby extending thepoint of the cam 17 upward, so as to take the place of the point of` thercam 18; but the useof the two cams is preferred; The piston being withdrawn just intime to receive the exhaustl passing in the directionof the VVarrows in Figs. 4 and 5 from the exhaust-port 2 into the casing 28 through the `raised exhaustvalve 12 into an outlet 4l and suitable pipe connection 42 into the inner l end of the cylinder 22, thesoundof the; exlhaust is entirely deade'ned. Thegradua'l action of the cams l17 and 18"'upon the lever' 19 ser-vesto force therpiston 24` slowly back -toi ward the closed end of the cylinder, and thusj the discharged gas slowly passes outthro-ugh .the discharge 27 without any noise. 5 .1 By means of the construction he-re shown thefexhaust-gases 'are neverr discharged directly into the atmosphere, Where theymake sufficient noise to frighten animals,- an'd thus render a gasolene-mo'ter `unfit for use upon lpublic vehicles of the various kinds. The dis-V charge being` received injavacuumor partial vacuum, completely deadens every sound` and the objection to a gasole'ne-inotor upon a car or'public vehicle of any kind-is entirelydone away with. f t, Y
